<p>
        This library may now be used in "standalone" mode without the rest
        of the Boost C++ libraries, in order to do this you must either:
      </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
            Have a C++17 compiler that supports <code class="computeroutput"><span class="identifier">__has_include</span></code>,
            in this case if <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">config</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span></code> is <span class="bold"><strong>not</strong></span>
            present then the library will automoatically enter standalone mode. Or:
          </li>
<li class="listitem">
            Define BOOST_REGEX_STANDALONE when building.
          </li>
</ul></div>
<p>
        The main difference between the 2 modes, is that when Boost.Config is present
        the library will automatically configure itself around various compiler defects.
        In particular in order to use the library with exception support turned off,
        you will either need a copy of Boost.Config in your include path, or else
        manually define BOOST_NO_EXCEPTIONS when building.
